Study investigates Nexium benefits patients with Zollinger-Elliso...( duals under constant attack from higher...),Health

duals under constant attack from higher than normal amounts of acid that their stomachs produce. Therefore, people with the condition require treatment that can continuously interfere with this faulty mechanism," said lead investigator David Metz, MD, Professor of Medicine, and the Director of the Acid-Peptic Program, Division of Gastroenterology, University of Pennsylvania Health System. "The study shows that NEXIUM provided early and sustained acid suppression to help control symptoms of the disease. These results corroborate previous research on the effectiveness of PPIs in treating gastric acid hypersecretion."

Study Details
The 12-month, open-label trial evaluated the effects of NEXIUM on basal acid output (AO) control in patients with ZES or idiopathic (of unknown cause) gastric acid hypersecretion (IGH). Patients (n=21) being treated with a PPI for ZES (n=19) or IGH (n=2) were switched to NEXIUM 40 mg twice daily (n=19) or NEXIUM 80 mg twice daily (n=2). At baseline and day 10, patients received a gastric analysis (i.e., basal AO test) to measure the amount of acid secreted by the stomach. Patients with controlled AO at day 10 remained on their current dose and were re-tested at three, six and 12 months. In those with uncontrolled acid, doses were titrated up to as high as 240 mg/day until AO was controlled. (Investigators could increase the dose of NEXIUM at their discretion throughout the trial.) Patients underwent an endoscopy at baseline, at six months and at 12 months to check for the presence of gastric or duodenal ulcers and/or erosive esophagitis. NEXIUM was generally well tolerated at all doses.
